#34054 [NEW]: pdo_mysql driver prepares all queries
From: jonathan+php at daikini dot com
Operating system: Mac OS X 10.4.2
PHP version: 5.1.0b3
PHP Bug Type: PDO related
Bug description: pdo_mysql driver prepares all queries
Description:
------------
Using MySQL 4.1.11
The pdo_mysql driver appears to attempt to prepare every query
that it processes. Unfortunately only certain query statement
types can be prepared in the current version of MySQL. See:
http://bugs.mysql.com/bug.php?id=6415
This is causing a failure in the example code posted.
Perhaps the pdo_mysql driver could look at the type of
statement it is processing and act accordingly and only
prepare statements that allow it or perhaps a new option or
method could be added so that it could be explicitly stated
that the query should not be prepared.
Reproduce code:
---------------
<?php
$db = new PDO("mysql:dbname=test;host=127.0.0.1", 'root', '');
$db->query('DROP TABLE IF EXISTS pdo_test');
$db->query('CREATE TABLE pdo_test (field1 int(11) default NULL, field2
varchar(20) default NULL)');
$query_that_should_not_fail = "SHOW CREATE TABLE pdo_test";
$result = $db->query($query_that_should_not_fail);
if (!$result) {
$errorInfo = $db->errorInfo();
print_r($errorInfo);
exit;
}
$row = $result->fetch(PDO_FETCH_ASSOC);
echo count($row);
?>
Expected result:
----------------
2
Actual result:
--------------
Array
(
[0] => HY000
[1] => 1295
[2] => This command is not supported in the prepared
statement protocol yet
)
